Answer;

- This statement about matter and its behavior is best classified as a Law.
-It is the Law of Universal Gravitation.

Explanation;
-The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation.This attractive force always points inward, from one point to the other.
-The Law applies to all objects with masses, big or small. Two big objects can be considered as point-like masses, if the distance between them is very large compared to their sizes or if they are spherically symmetric.

1.) if the total momentum for a system is the same before and after the collision, we say that momentum is conserved. if momentu
gogolik [260]

From the law of the conservation of energy;  the ratio of the total kinetic energy after the collision to the total kinetic energy before the collision must be 1.

<h3>What is momentum?</h3>

The term momentum is the product of mass and velocity. The principle of conservation of linear momentum states that total momentum before collision must be the same as the total momentum after collision thus the  ratio of the total momentum after the collision to the total momentum before the collision must be 1.

Also, from the law of the conservation of energy;  the ratio of the total kinetic energy after the collision to the total kinetic energy before the collision must be 1.

Of the three primary forms of subaerial volcanoes, ________ are large cone-shaped mountains that consist of alternating layers o
Alborosie

Answer:

Strato-volcano

Explanation:

Strato-volcanoes are usually characterized by the presence of steep-sided slopes, with distinct craters, and are frequently erupted and conical in appearance. This type of volcano is generally felsic in nature. Due to the presence of high silica content, the magma being highly viscous, moves at a relatively slower rate. These are highly explosive and produce a large number of pyroclastic materials, lava flow, volcanic ashes, and gases.

They are also commonly considered as the composite volcano, and are comprised of alternating tephra and solidified lava layers.

A boat is traveling at a speed of 36 km/h. It has to travel a distance of 210 km. How long will it take?
oksian1 [2.3K]

Answer:

If the boat is going 36 km/h, then it will take about 5.8 hours to travel a distance of 210 km/h.

Explanation:

To calculate time, you have to divide the distance by the speed.

In this case, we take 210 and divide it by 36. The answer you will get is 5.83...
